METAL WEATHER strair.

Application filed May 28. 1923. Serial No. 641329.

To all wlwnmlt may concern:

Be it known that I, ALFRnoM. LANE, a citizenzof the United States, and aresident of the city of St. Louis, andSt-ate of Missouri, have inventeda new and useful I-In- -provement in Metal Weather Strips, of whichthe-following is a specification. This invention relates to metalweather strips for windows. equipped withsliding sashes and has for itsprincipal object to produce a cheap and efiieient weather strip ofsimple construction and compact design which can be readily applied tosuch win: dows without- .material alteration thereof. Theinventionconsists in the parts and in "the arrangements and combinationsof parts hereinafter described and claimed.

In the accompanying drawing; wherein like symbols refer to like partswherever they occur,

Fig. 1 is a fragmentary horizontal cross section through one side of awindow casing and the adjacent portion of a lower sash provided with aWeather my invention; and

Fig. 2 is a hor zontal cross-section similar; to Fig. 1 showinga'weather strip of modified form.

Referring to Figs. 1 and 2 of the drawing, a portion of the casing orjamb member 3 of an ordinary window frame is shown as arranged for asliding sash 4, the respective walls of the vertical. slideway for thesash being formed by a parting strip or bead 5 and a stop member ormolding 6.-

Theweather strip shown in Fig. 1.00mprises cooperating metal strips ormembers .7 and 8 mounted-vertically on the jamb 3 and on the sash 4,respectively. The cooperating jamb strip 7 1s relativelyflexible orresilient and is secured along onemarginal portion to the jamb 3 of thewindow frame, as at 9, preferably under the stop member ormoldmg 6.silient jamb strip 7 extends between the opposing surfaces of the jamb 3and sash t and has. its opposite marginal portion offset laterally,adjacent to the outer vertical corner of the sash, as at 10, and thendoubled back upon itself for a suitable distance where itis again rebentparallel with the doubledback portion 10 and spacedtlierefrom to form anoutwardly opening grooved portion llof substantially U-shaped cross-'section. The free outer margin of the restrip embodying The flexible orre-- bent portion of the resilient jalnb strip '2' is then bent at rightangles to the walls of the groove to provide a flange-12. This flangeportion 12 works loosely in a vertical groove 13 provided thereforbetween the back face of the parting strip 5 and the adjacent wall 1member 3 of the window frame.

The cooperating sash strip member 8 is relatively rigid and is securedalong one margin to the outer face of the sash 4, as at of the grooveprovided therefor in the jamb 14, preferably inside of the inner face ofsaid parting strip or head 5. The opposite margin of this rigid sashstrip or member 8 is bent rearwandly at right angles to the body portionof the strip to provide a flange 15. This flange portion 15 projectsinto the groove portion 11 of the resilient jamb strip 7 and has a loosesliding fit therein.

In the construction illustrated in Fig. 2, the free marginal portion ofthe relatively flexible or resilient jamb strip 7 is bent inwardly andthence rearwardly, forming a rearwardly opening groove 11". .The metalforming the inner wall of the groove is then doubled back upon itselfand is then bent outwardlyacross the bottom of said groove to -.form aflange 12 which works loosely in the groove 13 provided therefor in thewindow frame or'jamb 3.

The free marginal portion of the relatively rigid sash strip 8" is bentaround the outer vertical corner of the sash and is then bent outwardlyand thence forwardly to form a flange or tongue portion 15? which has afree sliding fit in the groove 11 in the free marginal portion of theflexible frame strip 7.

It is noted that by the arrangements described, the cooperating tongueand groove portions of the two strips are effective in preventing draftsand keeping out dust and water. It is also noted that the jamb strip,owing to its resiliency, prevents binding and maintains a' weatherproofconnection be tween the two strips in the event that the sash swells,shrinks or is loosely fitted in the window frame. 7

Among the'advantages of my invention is the facility with which it maybe applied; In both cases the two members forming the weather strip havea slidable weather proof directly without any alteration of the windowframe or sash In addition to this, my invention is very easy to make andany broken or worn part may; be quickly'and easily replaced.

Obviously, the invention is not limited to,

use with the window" construction shown and described.

What I claim is.

1. The combination of a frame anda closure therefor, of a mctal'weatherstrip comprising two coopcrating'members mounted on said frame and saidclosure, respectively, the frame member comprising a metal strip locatedbetween the opposing faces of said frame and said closure and having afree marginal portion doubledback upon itself and formed'into a groovedportion having one wall of double thickness.

'2. The combination of a frame and a closure therefor, of a metalweather strip com-- )risin two coo eratin members mounted on' said frameand said closure, respectively,

the frame member comprising ametal strip located between the opposingfaces of said frameand said closure .and having a free marginalportion-doubled back upon itself and formed into a grooved portionhaving one wall of double thickness, the metal forming the other wall ofsaid grooved portion being bent at right angles to form a flange adaptedto work loosely in a groove provided therefor in said frame.

prising two cooperating members secured to said frame and said closure,respectively, the frame member comprising a metal strip located betweenthe opposing faces of said frame and said closure, and having a freemarginal portion that is doubled upon itself and is thence rebentoutwardly substantially parallel with said doubled-back portion-$0 forman outwardly opening grooved portion adapted to receive a portion of theclosure member.

4. The combination of a frame and a closure therefor, of a metal weatherstrip comprising two cooperating members secured to said frame and saidclosure, respectively, the frame member comprising a metal strip locatedbetween the opposing faces of said frame and said closure, and having afree marginal portion that is doubled .upon itself and 1s thence rebentoutwardly substantially parallel with said double-back portion to forman outwardly opening grooved portion adapted to receive a portion of theclosure member, the free outer margin of the rebent portion of saidframe member being bent at right angles to form a flange adapted to workloosely in a groove provided therefor in said frame.
